Application of FFT Periodogram to Flow Rate Measurement System
Journal Title: 河南科技大学学报（自然科学版） - Year 2016, Vol 37, Issue 3
Abstract
For the low precision and poor anti-jamming performance in measuring water flow via general methods,the fast Fourier transform( FFT) periodogram method was proposed. With digital signal processor as the main controller,FFT periodogram method was used to build water inrush velocity measurement system.Experimental analysis results show that the method not only can enlarge the range of measurement and reduce the flow limit measured values,but also improve the measurement precision and increase the noise robustness.
